From Bugzilla Helper:

Description of problem:
I have 3 Dell PowerEdge 2850 servers.  The on-board NIC (Intel Pro 1000 MT) doesn't auto-negotiate correctly with a Foundry Networks FastIron 2+ switch at gig full-duplex.  The NIC works fine with 10/100 ports; however, I don't even get a link light using the gigabit-only ports (the gig ports only support gigabit full-duplex).  Manually setting the NIC to gig/full-duplex (using ethtool) does not resolve the problem, nor does disabling auto-negotiation.

I suspected it was a driver problem.  I loaded Windows 2000 on the same box and installed the latest Intel drivers.  The same symptoms occurred at first under Windows, then I configured the driver and set 'Gigabit Master Slave Mode' to 'Force Master Mode' and the link came up.

I am not aware if the RHEL driver has a similar 'Force Master Mode' flag. I also experience this problem with RHEL4 as well as RHEL3u4.



Version-Release number of selected component (if applicable):
kernel- 2.6.9-5.0.3.ELsmp

How reproducible:
Always

Steps to Reproduce:
1. install RHEL3/4
2. plug NIC into Foundry FastIron 2+ switch
3.
  

Actual Results:  no link light, NIC does not pass traffic

Expected Results:  link light & NIC to work
